Hydraulic head (Hydrology 💧)

Hydraulic head or piezometric head is a measurement related to liquid pressure and the liquid elevation above a vertical datum. It is usually measured as an equivalent liquid surface elevation, expressed in units of length, at the entrance of a piezometer. In an aquifer, it can be calculated from the depth to water in a piezometric well, and given infor...

Hydraulic head (Hydrology 💧)

Hydraulic head or piezometric head is a specific measurement of liquid pressure above a vertical datum. It is usually measured as a liquid surface elevation, expressed in units of length, at the entrance of a piezometer. In an aquifer, it can be calculated from the depth to water in a piezometric well, and given information of the piezometer's elevation...

Drawdown (hydrology) (Hydrology 💧)

In hydrology, there are two similar but distinct definitions in use for the word drawdown: In subsurface hydrogeology, drawdown is the reduction in hydraulic head observed at a well in an aquifer, typically due to pumping a well as part of an aquifer test or well test. In surface water hydrology and civil engineering, drawdown refers...
